RAS to GRAYA Converter
Processing entirely on your device — large files may take a moment.
RAS is the Sun Raster image format of old Solaris workstations — a minimal header plus raw pixels, still common in legacy UNIX image archives. Convert to GRAYA when a pipeline needs bare pixel bytes.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the RAS format
The Sun Raster coder of the ImageMagick set — the unix-archive format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing

There is a concrete reason this conversion exists: Niche format — few modern readers GRAYA sidesteps that — Written natively by ImageMagick If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this RAS to GRAYA converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting RAS to GRAYA?
No — GRAYA is a lossless format, so every pixel of the converted image matches your original RAS file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several RAS files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your RAS files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
